The correct answer is: C. Both planimetric and height control.
Triangulation is
a surveying method that uses the principles of geometry to measure the distance between points on the Earth’s surface. It is a very accurate method of surveying, and it is used for a variety of purposes, including:- Mapping the Earth’s surface
- Building construction
- Engineering projects
- Land surveying
Triangulation works by measuring the angles between three or more points. The distances between the points can then be calculated using trigonometry.
Planimetric control is the control of horizontal positions. It is used to establish the horizontal position of points on a map or plan. Planimetric control is usually obtained by measuring the angles between points and the distances between points.
Height control is the control of vertical positions. It is used to establish the vertical position of points on a map or plan. Height control is usually obtained by measuring the elevations of points.
Triangulation can be used to provide both planimetric and height control. This is because the angles between points can be measured to
a high degree of accuracy, and the distances between points can also be measured to a high degree of accuracy.Here are some additional details about each option:
- Option A: Planimetric control is the control of horizontal positions. It is used to establish the horizontal position of points on a map or plan. Planimetric control is usually obtained by measuring the angles between points and the distances between points.
- Option B: Height control is the control of vertical positions. It is used to establish the vertical position of points on a map or plan. Height control is usually obtained by measuring the elevations of points.
- Option C: Both planimetric and height control. Triangulation can be used to provide both planimetric and height control. This is because the angles between points can be measured to a high degree of accuracy, and the distances between points can also be measured to a high degree of accuracy.
- Option D: None of these. Triangulation can be used to provide both planimetric and height control.
